Definitions
- the present invention relates to a catalyst arrangement for Exhaust systems of motor vehicles, in particular with Otto engine, with the 4.
- Catalytic converter for converting exhaust gases into one Sheath arranged, a plurality of channels through which a fluid can flow having honeycomb bodies are, for example, by EP 0 049 489 B1 known.
- the honeycomb bodies preferably consist of sheet metal layers, wherein at least some of the sheet metal layers are at least partially structured is.
- the sheet metal layers with their structures delimit channels that run from a fluid can flow through.
- Catalytic converter arrangements for exhaust systems are known in which the Exhaust gas at least in some areas of the exhaust system in at least two separate systems.
- For the catalytic conversion of the exhaust gas is in every system at least one catalytic converter with axially extending Channels arranged.
- EP 0 245 738 B1 describes a catalytic converter arrangement for exhaust systems known from motor vehicles in which the exhaust gas at least in some areas the exhaust system is managed in at least two separate systems, with at least one axial catalytic converter in each system extending channels is arranged. These catalytic converters are in arranged in a common housing.
- EP 0 245 738 suggests this B1 intends to use honeycomb bodies that have independent segments within form a common housing. The individual segments can by suitable pipe routing assigned individual exhaust lines of an exhaust system become.
- EP 0 245 738 B1 proposed the converter consisting of individual honeycomb bodies build up that form a corresponding total honeycomb body. The individual segments have a jacket, with the additional supporting walls are connected. The jackets of the individual segments are joined together connected, creating a total honeycomb body.
- JP 10 12 017 is also a catalyst arrangement for exhaust systems known from motor vehicles, in the exhaust gas at least in some areas the exhaust system is managed in at least two separate systems, with at least one axial catalytic converter in each system trending channels is arranged and this catalytic converter in are arranged in a common housing, the catalytic converter form a single honeycomb body on at least one end face at least one partition dividing the cross section of the housing has, which is at least almost sealingly brought up to the end face.
- the honeycomb body is made of Layers of at least partially structured sheets is built up. At least part of the sheets extends over the entire axial length of the Honeycomb body. These sheets divide the honeycomb body microscopically into individual channels through which a fluid can flow. For the macroscopic Subdivision of the honeycomb body into at least two independent exhaust gas lines, through which exhaust gases can flow without mixing the exhaust gases take place in the honeycomb body, no additional partition walls are required, which extend over the entire axial length of the honeycomb body. For separate flow through the single honeycomb body is the Converter with at least one end face of the honeycomb body at least a partition dividing the cross section of the housing is provided.
- the previously separated exhaust gas flows up to Inlet cross section of the honeycomb body through the partition in the housing still separated.
- the partition is at least almost sealed to the Front of the honeycomb body. This creates a thorough mixing the exhaust gases of the individual exhaust gas lines avoided. This is particularly so for the fluidic design of the exhaust system in With regard to the loading of the combustion chambers of the power machine from Meaning.
- honeycomb bodies are relatively complex, in particular if several are separated by the honeycomb body for a given installation volume leading exhaust lines are necessary because the geometry of the individual segments becomes relatively complicated.
- the present invention is based on the object to provide an easy to manufacture catalyst arrangement, the separate Exhaust gas routing suitable for individual exhaust lines of an exhaust system is. Another goal is to reduce the manufacturing overhead of a converter to reduce such an arrangement for catalytic conversion.
- a first proposed solution of a catalyst arrangement according to the invention for exhaust systems of motor vehicles is characterized in that the Partition protrudes into a slot in the side of the honeycomb body.
- the honeycomb body is advantageously used to seal the partition Honeycomb body also increases with alternating thermal loads without the Honeycomb body can be damaged in the case of relative expansion of the partition.
- honeycomb body By making the catalytic converter a single honeycomb body, can also previously known honeycomb body to form the only one
- the honeycomb body of the catalyst arrangement according to the invention is used become.
- This proposal has the advantage that the existing, through the subdivision of the honeycomb structure in interaction with the sheet metal layers with the partition, can be used.
- the previous tools for the Production of such a honeycomb body can continue to be used. This simplifies the manufacture and thus also the manufacturing costs of a honeycomb body according to the invention.
- the partition is preferably attached to the housing.
- the partition runs preferably diagonally in the connection flange or cone.
- Of the Slot on the end face of the honeycomb body can, for. B. by spark erosion be formed in the honeycomb body.
- the partition forms with the wall the slot of the honeycomb body a sliding seat. To avoid An exchange of the exhaust gases between the individual exhaust lines is the Sliding seat preferably designed almost sealing.
- the To build a partition in two parts with a first part of the partition is attached directly to the honeycomb body itself and seals with a sliding seat cooperates with a second part of the partition, which is on the housing or is attached to the connecting flange.
- a first part of the partition is attached directly to the honeycomb body itself and seals with a sliding seat cooperates with a second part of the partition, which is on the housing or is attached to the connecting flange.
- the honeycomb body is preferably a monolithic, metallic honeycomb body, that of wound or layered, at least partially for Formation of the channels structured sheet metal layers is formed.
- connection element At least partially protrudes into the honeycomb body.
- the connecting element preferably has a cross section and / or a Form that is or are designed so that the or the connecting elements inserted into selected and / or any channels mechanical Has or have contact with their walls.
- a preferred embodiment of the device is one in which each partition wall a connecting element is rigidly connected and possibly further Fasteners each form a sliding seat. Training the sliding seat has the advantage that different stretching behavior balanced of the honeycomb body and the partitions or the partition can be without the connecting elements in the partition or forces are introduced into the honeycomb body.
- the device has at least one Partition on, which forms a closed line, the area of the closed line is smaller than the entrance cross-sectional area or exit cross-sectional area of the honeycomb body.
- Prefers is a closed line, which is circular.
- the attachment of the Partition with the honeycomb body also take place in that this at least one extending over part of the axial length of the honeycomb body Has slot into which the partition protrudes.
- the partition preferably has a first part, which is U-shaped in cross section with a base and two webs connected to the base is formed, the base is facing the honeycomb body.
- the U-shaped cross section Partition is connected to the honeycomb body so that the base the partition faces the honeycomb body.
- the webs protrude on Inlet cross section against the flow direction of an exhaust gas. Between the webs are the second part of the partition with sliding seat. This results in a different expansion behavior due to temperature expansion balanced.
- the partition walls are preferably on both end faces of the honeycomb body educated.
